Promoting Physical Activity Among Young Children With Autism

Higher amounts of physical activity are linked to multiple health benefits including improved cognition, academic success, and classroom behavior for children. These relationships start in early childhood during the preschool years. Additional research is needed to determine the rates of physical activity among children with autism spectrum disorder. However, research suggests that compared to their typically developing peers, children with autism participate in fewer types of physical activities, often have delays in a range of motor skills, and face physical activity barriers including behavior problems, social communication challenges, and adults' uncertainty about how to modify physically active games to include them. Young children need adult guidance, support, and opportunities to be more active, and early care and education programs are a critical setting for physical activity promotion.

Faculty at Northeastern University developed and pilot tested WE PLAY (Wellness Enhancing Physical Activity for Young Children), a teacher training, that is accessed online at no cost. WE PLAY was designed to promote physical activity at the child-level, to promote knowledge, confidence, and skills to lead active play at the teacher-level, and to impact social and environmental challenges at the program-level. Three three pilot studies demonstrated that WE PLAY was efficacious in increasing physical activity when implemented with preschoolers with and without autism and it was viewed as feasible, understandable, and acceptable by early childhood educators.

This clinical trial will test the efficacy of WE PLAY in children with autism spectrum disorder and their teachers. The researchers hypothesized that at post-training and follow-up, children in the WE PLAY group will engage in higher levels of physical activity in school relative to children in the control group. Further, the researchers hypothesized that at post-training and follow-up teachers in the WE PLAY group will demonstrate increased behavior intentions, perceived behavior control to perform physical activity facilitating behaviors relative to control group teachers. Additionally, this study will explore the effects of malleable teacher and system-level factors between the intervention and child physical activity. The researchers hypothesized that malleable teacher and system variables including behavior intentions, perceived behavior control, physical activity promotion practices, teachers' perceived physical activity promotion role, teacher autonomy, and supervisor support will mediate or moderate the relationship between study group and child physical activity levels.

A national sample of 150 teacher-child dyads from early childhood education programs across the United States will be randomized into two conditions (WE PLAY vs. Control). Data will be collected across three periods over 20 weeks (pre-training = 0 weeks, post-training = 4 weeks, follow-up = 20 weeks). WE PLAY teachers will be asked to complete the WE PLAY training. Control group teachers will complete another online training on a topic that is not related to physical activity. Children with autism (ages 2.9 to 5.11) will wear accelerometers during waking hours for five consecutive days at each of the three data collection periods and their teachers will complete online surveys at each of the three data collection periods.

The proposed study addresses a critical need for young children with autism. If WE PLAY is determined to be efficacious on a large scale it would lead to interventions that could be integrated in a variety of settings, including early care and education programs and community settings, which could improve physical activity levels in young children, setting them up for greater success throughout their lives.
